JAMES SCOTT, OF ARAPAHOE COUNTY, COLORADO.

AMALGAMATOR.

SPECIFICATION forming part of Letters Patent No. 243,802, dated July 5, 1881.

J Application filed January 13, 1881. (ModeL) I do hereby declare that the following is a full,

clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a perspective view; Fig. 2, section view.

A is the frame of the machine. B is a double sieve or rocker hung on pivots connected by a crank and rod to give it a rocking motion. The rocker is a box with solid bottom, having an outlet at one end, and two perforated sieves, which may be made by punching or drilling holes in metal, or by la iug bars of iron across the box, and are adjustable to different angles, according to the kind of dirt running through, each having an orifice for disposing of refuse.

O O O O are amalgamating-plafes, set on an incline to allow dirt and water to flow off.

D D are a set of corrugated rolls.

E E are disks of amalgamated copper cut and bent to form wings, and are set in a trough 0 or box and rotate, thereby mixing up the mud.

F is a four-leaved fan set with magnets. G G is a fan set so as to mesh in F and rotate it.

The operation of the machine is as follows: 5 The dirt and water are thrown in B, the bowlders passing out at K, the finer portions pass ing through the sieve H. The dirt is then passed through a still finer sieve, I, then down M onto amalgamating-plates, the refuse passing out at L. The dirt and water flow over amalgamating-plate 0 through roller D D,

which thoroughly crushes it, and should any rusty gold, or gold embedded in sand, rock, or other substance, be present, new surfaces will be formed, thereby giving the amalgamation it, dropping off as it rotates, the black sand and rusty gold beingwiped off by fan G and deposited on the other side.

I am aware of the patent to Testman, No. 56,636, July 24, 1866, and I claim nothing therein shown.

I claim 1. In an amalgamator constructed substantially as described, the fan Gr, having amalgamated flat wings or leaves, as herein described, for the purpose set forth.

2. In anamalgamator, thecombination, with the fan F, having magnetic wings or leaves, of the amalgamated fan Gr, arranged to remove from fan F the black sand or rusty gold which may adhere to the latter, as set forth.

3. The magnetic fan F, arranged as herein described to intersect and be operated by the leaves of an amalgamated fan, G, for the purpose shown and specified.

4. In an amalgamator, the crushing-rollers D D, fluted or corrugated, as shown, and arranged between the inclined amalgamated plates O 0 as herein described, for the purpose set forth.

5. The combination of the box B,sieves H and I, plates O O 0 0 rolls D D, wing fans or mixers E and E magnet-wheel F, and fan G, for the purposes set forth and specified.
